Avoid Blisters on PIR/PUR Panels with the SikaMelt®-285 Primer

Our SikaMelt®-285 Primer was developed to improve adhesion of PUR/PIR foams to coated or bare metals used in foam injected panels. Thus, avoiding blisters caused by thermal shocks. With nearly zero blisters, significant cost savings are achieved by the improved panel quality which leads to a reduction in claims.   

Since our primer solution is free of solvent and isocyanates, it is classification-free, making it an excellent replacement for conventional primers.  

Additionally, it offers the flexibility to be used in continuous or discontinuous production and it can easily be retro-fitted to existing production lines. 

The combination of excellent technical performance, cost efficiency and simplicity of application makes the SikaMelt®-285 Primer an excellent solution for the production of PUR/PIR foam panels.
